In visual physiology, adaptation is the ability of the retina of the eye to adjust to various levels of light. Natural night vision, or scotopic vision, is the ability to see under low-light conditions. In humans, rod cells are exclusively responsible for night vision, as cone cells are only able to function at higher illumination levels. [1]

In general, carotenoids absorb wavelengths ranging from 400 to 550 nanometers (violet to green light). This causes the compounds to be deeply colored yellow, orange, or red. Carotenoids are the dominant pigment in autumn leaf coloration of about 15-30% of tree species, [ 3 ] but many plant colors, especially reds and purples, are due to ...
Whether you can't seem to stay away from the taste of sprite, or you resort to a can of coke for a midday pick-me-up -- you know what it's like to enjoy the sweet taste of soda throughout the day.
When ripe, it turns a light yellow. Its flesh is juicy and sweet with a slightly sour taste. [1] It is usually eaten cut up, sprinkled with sugar and with most of its rather thick pith intact. [citation needed] The fruit's oil is higher than other citrus fruits in trans-β-farnesene, l-carvone, and has a higher number of ketones. [2]
In a pilot study, the implant – made from collagen protein from the animal – restored vision to 20 people with diseased corneas, most of whom were blind prior to receiving the implant.
